        23
      • 3. Press the appropriate numerical key(s) for the correct hour. When the correct hour flashes on the display, press YES. This will cause the minutes to flash on the display.

        23
      • 4. Using the same procedure, select the correct minutes and press YES. The am/pm indicator will flash.

        23
      • 5. If the desired indicator is flashing on the display, press YES. If the desired indicator is not flashing, press NO. This will cause the other indicator to flash.

        23
      • 6. Press YES. The month will begin to flash. Select the correct day, month and year using the same procedure as you used to set the time.

        23
      • 7. After the correct year has been entered, the display will read "Synchronize Time-enter at Time". Pressing YES will start the clock. The display will read "Clock is Now Set".

    • 2. Press NO to cause other volume units to appear. When the desired units appear on the display, press YES.

      23
    • 3. The display will show "Volume = _ _ _ _ _ mL" (or "Volume = _ _ _ _ _ Gallons"), whichever was chosen in the previous step.

      23
    • 4. Enter the volume for the individual sample bottle by pressing the numerical keys.

      23
    • 5. Press YES to accept the volume.

        25
      • 2. To operate the pump, press either the PUMP or PURGE key. This will cause "Manual Mode - Pump/Purge/Clear" to appear on the di...

        25
      • 3. To run the pump continuously in either direction without having to hold down the PUMP or PURGE keys, press the * key. This will cause "Lock-Pump/Purge" to appear on the display. Then press either PUMP or PURGE.

        25
      • 4. To stop the pump, press STOP PUMP or turn the sampler off with the OFF key. Pressing STOP PUMP returns the display to "Pump/Purge/Clear".

        25
      • 5. To exit the manual mode, press CLEAR ENTRY. This returns the sampler to the standby state.

      • 3. Disconnect all tubing.

        33
      • 4. Place the controller, face down, on a cloth-covered workbench to prevent scratching the front panel.

        34
      • 5. Inside the Center Section, remove the four screws that fasten the Controller.

        34
      • 6. Lift the Center Section off the controller.
